Create audio plugins on-the-fly with LuaJIT.
Protoplug is a VST/AU plugin that lets you load and edit Lua scripts as audio effects and instruments. The scripts can process audio and MIDI, display their own interface, and use external libraries. Transform any music software into a live coding environment!
Cross-platform: builds for Windows, Mac OS X and Linux. This means that all protoplug scripts are compatible with these platforms and can be loaded into a huge amount of audio software (glory to JUCE).
Fast: Use the speed of LuaJIT, and perform DSP tasks as efficiently as old school C implementations.
Free and open source: Want a new feature? Add it yourself. The source is MIT-licensed and available on Github.
